The situation you mention can be caused by the browser itself that is breaking when playing the videos. I recommend you testing a different browser and uninstalling the driver you have and reinstalling it but doing the manual installation. Here are the steps:
The step of reinstalling the Operating System can be done in the worst case but if there is a problem with the registry of the Operating System it may be necessary to do this step.
Also, you can try with another processor in the motherboard if possible would be another good step to take.
